This is something we've not tried yet, so I don't know. I would be surprised if it worked right now. But in general, it's something we would definitely be interested in exploring.

The containers created by Sysbox act like virtual-hosts, so it makes sense to have the ability to expose GPUs / hw-accelerators within them. But container nesting, which comes naturally with Sysbox, would introduce another challenge since the GPUs would not just need to be passed to the outer system container, but also to the inner application containers.
